MAP file examples

Quote from Dave Taylor (IRC, 1995)

You will note that this is different from the current MAP file format. Guessing, the number of vertices and the texture is given, followed by texture mapping parameters, and the vertices. While four vertices are sufficient to define a (sheared, rotated) cube, I guess each line defines a plane. However, this format, while quoted on some pages, is obviously not used anymore.

here's some lines from a map file...

   4 WALL14_5 0 0 0 0 0 0
     (0,912,176,144) (0,928,176,144) (16,928,176,144) (16,912,176,144)
   4 WALL14_5 0 0 0 0 0 0
     (192,928,144,0) (192,1040,144,0) (208,1040,144,0) (208,928,144,0)

it's like coordinates specifying a brush and a texture and some other 
stuff.

Example from John Carmack (e-mail, april/04/96)

Here is the contents of johnc99.map, a simple box room consisting of six brushes on the world (the entity #0), and three other entities without brushes ("info_player_start", "light", and "info_player_deathmatch"). Note that it takes six cubes (brushes or building blocks) to define on box volume, and each brush has six planes, the intersections of which define the surface of the brush.

To clarify, in this revision of the MAP file format, the trailing zeros in a plane like

  "( 0 816 0 ) ( 0 512 0 ) ( 16 512 0 ) TECH07_2    0 0 0"

are s_ofs, t_ofs, and flags. I.e. a texture offset s_ofs=16, t_ofs=-32, with negate_s, negate_t, and exch_st all set will read

  "                                 ... TECH07_2    1 -2 7 1.0 1.0"

instead. Note that texture offsets are currently multiples of 16.

This is, hoever, not the current MAP format, as in the jrbase1 MAP file (670K) from the shareware version (released with the QuakeEd source) there are two floating point numbers added to each Plane definition, which are probably dummies right now, and the flags have vanished.
